Functional Programming is often seen as a nice tool for small-scale concerns, not as a tool for application design. "Functional in the small, OO in the large" is often heard and sums up this idea quite well. However, functional programming comes with interesting tools aimed at solving these boring (or deemed boring) concerns: dependency inversion, observability). Aspect-Oriented-Programming is often used for this in the OO word.
A functional solution, called a monad stack, allows to combine all this cross-cutting concerns and behaviours with no magic (or not too much).
In this conference, we'll see what monad transformers are, how they work, and how to use them to structure a web application, with examples in scala and haskell.
React and flux have shown us how to design UI in a modular fashion. One of the core ideas, is that data should always flow in one direction. With this concept, it's easier to build applications from independent modules. I'll show what react core concepts are and how they allow developers to manage complexity in big applications.
At the end of the talk, you'll have a basic understanding of how Flux works, you'll know how RxJS works and how you can use FRP to design your client side applications.
